Description
The present invention relates to an arrangement for a vehicle-mounted
load-carrier for a cycle or some other similar load, which is capable of
attachment in an upright attitude to a cycle supporting bar or a similar
holding element capable of being connected to the load-carrier, said
load-carrier and cycle supporting bar, etc., being so arranged as to be
clamped together by means of securing devices capable of adjustment along
the cycle supporting bar in question and straddling same.
Previously disclosed arrangements intended to permit cycles and similar
loads to be supported on load-carriers on vehicle roofs do not permit
rapid securing to or rapid release of the cycles in question from the
load-carrier, nor do they permit the simple securing of cycles to
different vehicles on which load-carriers are positioned at varying
distances from one another.
The principal object of the present invention is thus, in the first place,
to solve said problem by simple, yet secure means.
Said object is achieved by means of an arrangement in accordance with the
present invention, which is characterized essentially in that the securing
device includes a clamping arm for securely clamping the load-carrier and
capable of actuation by means of an adjuster, with the clamping arm and
the adjuster being pivotally mounted on a sleeve-shaped carrier for the
securing device.
The invention is described below as a number of preferred illustrative
embodiments, in conjunction with which reference is made to the
accompanying drawings, in which:

FIG. 15 shows the wheel attachment element in the closed position.
An arrangement 1 for a load-carrier 2 for cycles 3 or other similar loads,
which is intended to be supported by a vehicle, with the cycles 3, etc.,
being capable of attachment in an upright attitude to the roof with the
help of a number of cycle supporting bars 4 or similar holding elements,
which are so arranged as to be capable of being connected to the
load-carrier 2 in question, comprises securing devices 5 of the kind
illustrated in the drawings. The load-carrier 2 and the cycle supporting
bar 4 are so arranged as to be clamped together by means of such securing
devices 5, for which purpose the securing devices 5 are so arranged as to
straddle the cycle supporting bar 4, etc., in question and to be
adjustable along same. The securing device 5 comprises a clamping arm 6,
which is capable of actuation by a manually operated adjuster 7, which
clamping arm and adjuster are pivotally mounted on a sleeve-shaped carrier
8 for the securing device. The securing device carrier 8 is so arranged as
to be capable of being slid onto the cycle supporting bar 4, etc., in the
direction of the arrow 9, as shown in FIG. 5, in order to be displaced
along the bar 4 and into the desired adjustable position next to a
transverse load-carrier 2, so that the clamping arm 6 can engage from
below around the load-carrier 2 for the purpose of securely clamping the
load-carrier 2 and the bar 4 to one another. The shape of the clamping arm
6 is appropriately adapted to the peripheral part of a load-carrier in
question and exhibits a front part 10 which extends at an angle upwards
from a bottom part 11, which in turn is angled in relation to an ascending
holding part 12.
By means of the front part 10, which is so arranged as to interact with the
wall part 13 of a load-carrier 2 along at least its lower part, an attempt
is made to cause the load-carrier 2 and the securing device to move in a
direction towards one another, in a relative sense.
The securing device carrier 8 appropriately exhibits a stop 14 capable of
interacting with a load-carrier bar 2 of the kind in question, which stop
reaches down below the upper roof part 15 of a load-carrier bar in
conjunction with the fastening together of the arrangement 1.
The clamping arm 6 is pivotally mounted in the direction of the arrows 18,
19 at the upper end 12A of the holding part 12 via a bearing 16, which is
accommodated in the vertical side walls 17 of the securing device carrier.
At the transition between the bottom part and the holding part 11, 12, a
link 20 or some other appropriate movementtransmission device is pivotally
mounted about a bearing 21 to either side of the clamping arm 6, which is
also attached to the adjuster 7 via the bearing 22, which is accommodated
in the outer part 23 of the adjuster 7. The adjuster 7 is in turn
pivotally mounted on the securing device carrier 8 via bearings 24 which,
like the bearings 22, are similarly accommodated by vertical arm-like side
walls 25 on the adjuster 7, which side walls are situated at a certain
distance from one another.
The adjuster 7 is thus supported in such a way that it exhibits a so-called
over-center function, that is to say the position of the bearing 22 is
varied to either side of an imaginary line 26 passing through the bearings
21, 24, with the adjuster respectively in the open and closed position.
The adjuster 7 can appropriately exhibit a locking device 27, which can be
so arranged, for example through the effect of a key 28, as to be capable
of interacting with a matching locking element 29 supported by the
securing device 5 on its carrier 8. The locking device can be in the form
of a moving tongue 27, for example, which is capable when in the locked
position of being accommodated in a suitable recess 29.
The securing device 5 can also exhibit anchorage devices 30 for
accommodating or in some other way interacting with a locking wire 31 or
similar, by means of which a cycle 3, etc., can be attached to a
load-carrier 2 and a cycle supporting bar 4 for the purpose of preventing
the theft of the cycle 3, which in this way is locked to the vehicle after
locking the securing device 5. The anchorage device may consist of, for
example, a slot-shaped wire-accommodating opening 30, which extends
through and along the end wall 25 of the securing device, so that a
wire-accommodating opening is formed on the upper part of the securing
device 5 between the securing device carrier 8 and the swinging arm 7 and
is capable of accommodating an aforementioned endless wire loop 31, for
example, after it has been passed around a cycle 3 mounted on the vehicle.
The function of the securing devices should have emerged from the
foregoing, and securing devices 5 can appropriately be used in pairs for
the respective cycle supporting bars 4 turned in relation to one another
so that the swinging arms 7 are easily accessible between the load-carrier
bars 2.
No restriction, beyond the length of the cycle supporting bar, is embodied
in the idea of invention, and the securing device 5 can be displaced
freely in its clamped position along the cycle supporting bar 4 in order
to be adapted to the actual distance L set between the load-carrier bars
2.
The attachment of a cycle 3 or some other similar load in an upright
attitude to a cycle supporting bar 4 or some other similar holding element
capable of being connected in a removable fashion to a load-carrier 2
supported on a vehicle can take place appropriately by means of U-shaped
attachment elements 32, 33, 34, which exhibit means 35, 36, 37 for
securing to a cycle, etc., 3.
The remaining side 38 of the cycle supporting bar is arranged by means of
quick-action attachment element 32 in such way that the attachment element
32 is securely clamped around the cycle supporting bar. The bottom 40 of
the load carrier 2 is arranged to be clamped by the securing device 5 to
the cycle supporting bar 4.
Attachment elements 32, which at their upper surface exhibit a recess 35 to
accommodate the wheel 42, which attachment elements are attached to the
cycle 3 in question, are each provided with a transcurrent opening 43 in
the side 44 for the purpose of accommodating an enclosing cycle supporting
bar 4 introduced from the side of the cycle supporting bar, etc., 4. A
preferably flexible quick-action clamping device 41 is so arranged, when
in the locked position I, as to bridge said opening 43 and to engage
around the aforementioned wheel 42 accommodated in the recess 35.
The quick-action clamping device, which is preferably constituted by an
endless loop 41, preferably a plastic-coated wire made of metal, for
example, or some other suitable material, and which exhibits at its outer
part 45 a wear protector 46, which is formed into a loop, is so arranged
as to be capable of being attached to the attachment element 32 at a
certain distance from one another with their respective end parts 45, 47.
One end part is held in a movably supported clasp 48, which is pivotally
mounted via a bearing 49, which is situated on the outside of the end wall
50 situated away from the introduction opening 43, so that an over-center
effect is achieved.
The opposite end 46 of the quick-action locking device is capable of
removable attachment to a locking device fastener 52 situated on the under
side 51 of the attachment element at a certain distance from the clamping
bearing 49. The locking device fastener is formed preferably from a number
of recesses 53, 53.sup.A, 53.sup.B, 53.sup.C arranged in a row, in which
matching recess, the end 46 of the quick-action clamping device can be
accommodated for securing to same after snapping the clasp 48 into
engagement. Receiving channels 54, 55 extend to either side of the
recesses 53--53.sup.C for the purpose of accommodating parts 41A, 41B of
the quick-action clamping device.
Irrespective of the width of the wheel 42, the quick-action clamping device
41 is able to clamp it and the attachment element 32 securely by
positioning the quick-action clamping device 41 in the desired recess
53--53.sup.C and locking it by means of the clasp 48.
Said quick-action clamping device 32 can easily be applied to, and released
from the cycle supporting bar 4 in question, and can be displaced into the
desired position along a cycle supporting bar 4 in order to be able to
adapt the width between the cycle wheels 42 in the case of cycles of
varying size without having to actuate knobs or screws, etc.
One attachment element 33, which is so arranged as to be capable of being
attached rapidly in a removable fashion to the frame of a cycle 3 via
stays 56 and securing means 36, can exhibit above its carrier 57, which is
preferably of U-shaped cross-section, a receiving part 58 between two
travel-restricting heels 59, so as to be capable of holding a cycle
supporting bar, etc., 4 without the risk of their being displaced
laterally relative to one another in the clamped position, as shown in
FIG. 2.
Said part 58, as well as a clamping part 60 on the attachment element 34,
are so arranged as to be clamped securely between the load-carrier 2 and
the cycle supporting bar, etc., 4 through the effect of the securing
device 5.
The invention is not restricted to the illustrative embodiment described
above and illustrated in the drawings, but can be modified within the
scope of the Patent Claims without departing from the idea of invention.
